Wirecutter's oil-filled pick: silent, sturdy, and it keeps a room warm long after switching off. But it can take half an hour or more to feel any warmth, the case reached 180°F in testing, it's a 25 lb suitcase-sized unit, and Amazon owners report a burning-chemical smell and some early failures.
Top complaints
- Very slow to warm up
Wirecutter says it can take a half-hour or more before you feel any warmth, and even after an hour it might raise the room by only a few degrees.
Source: Wirecutter - Burning or chemical smell
Odor is a mixed aspect on Amazon, with some owners reporting a burning chemical smell. Wirecutter says new oil-filled radiators can give off a stench from leftover manufacturing oil that should fade.
- Hot surfaces, bulky, some early failures
Wirecutter measured the case at 180°F after four hours, hot enough to burn skin, and notes it weighs 25 lb, is suitcase-sized and can be top-heavy. Reliability is mixed on Amazon, with some owners saying it stopped working after two weeks. The warranty is just one year (Wirecutter).
What owners love
- Completely silent
With no fan, Wirecutter says it makes no extraneous noise at all.
Source: Wirecutter - Holds heat for hours
Wirecutter's test room stayed between 80°F and 90°F for four hours after the power was off. Amazon owners praise the temperature control and say it cycles to hold the set temperature.
- Sturdier and cooler than rival radiators
Wirecutter calls its all-metal build more durable than plastic heaters and more balanced, and cooler to the touch, than other radiators it tested. Amazon owners note automatic shutoff in overheating or freezing conditions.

What experts say
- Wirecutter (NYT): Best oil-filled radiator: silent, long-lasting heat and a sturdier, cooler build than rivals. Downsides are a very slow warm-up, its size and 25 lb weight, a 180°F case, possible new-oil smell and a one-year warranty. The analog TRD40615T is near-identical.
